ABSTRACT:
A linear guide apparatus includes end caps respectively joined to opposite ends of a slider main body. In each of the end caps, a feed oil channel is formed in the joining end surface thereof to feed lubricating oil to balls rolling in ball rolling paths from a feed oil nipple. Band-shaped protrusions are formed on lands at both sides of the feed channel integrally with the end cap at the time of injection molding of the end cap of synthetic resin. When the end cap is fixed to the slider main body by clamping a screw, the band-shaped protrusions are deformed elastically to fill up a minute gap existing between both end surfaces of the end cap and the slider main body to prevent leakage of the lubricating oil.
